There's concern in women's groups in Tonga that next week's election may once again result in no female candidate winning a seat.

Only five women have been elected to Parliament since 1951, and no woman won a seat in the last general election in 2014.

'Akosita Havili Lavulavu won the Vava'u by-election last year, and remains the only woman in parliament.

A field of 15 well-regarded women is standing for election on November the 16th, Ofa Guttenbeil-Likiliki of the Women and Children's Crisis Centre says the biggest hurdle they face is how to change attitudes towards having women in parliament.
